Examples of ReverseDependencyOrderWalker

org.apache.pig.experimental.plan.ReverseDependencyOrderWalker
Visit a plan in the reverse of the dependency order. That is, every node after every node that depends on it is visited. Thus this is equivalent to doing a reverse topilogical sort on the graph and then visiting it in order.
